RELASTlNG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 651 ,405, dated June 12, 1900.

Application filed April 8, 1895. Serial No. 544,889. \No model.)

To all whom it may concern.-

Be it known that we, ERASTUS E. WINK- LEY and BENJAMIN PHILLIPS, citizens of the United States, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Relasting-Machines, of which the following, taken in connection with the accompanying drawings, forming a part hereof, is a specification.

This invention relates to improvements in machines of the above class; and it consists of a device whereby a driving-pulley constantly driven in one direction is arranged to actuate the working parts and of improvements in the horn-controlling mechanism, as hereinafter more specifically set forth and claimed.

The objects of this invention are to substitute power for pedal operation of the machine, as heretofore practiced, and to secure an easy movement for the horn, which will prevent liability ofinjury to the shoe during the operation of the machine.

This invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a machine embodying our invention. Figs. 2 and 3 are respectively a partial side and front view showing the connection of the driving-pulley with horn-operating mechanism. Fig. at is a detail of rack and connections.

In the drawings, A represents the usual last-supporting post, which is conveniently provided with a spindle 1, as common in machines of this class.

2 represents the shoe-horn, shown as rigid and pivoted at 3 to its operating-rod 4. The horn 2 may, however, be of the flexible-shank type and may be attached to the rod 4 in any suitable manner, such features forming no part of the present invention.

The horn-actuating mechanism in which we have embodied our invention, as shown in the drawings, is described as follows: The horn-operating rod at extends through the elongated slot 5 in the arm 36, laterally proj ected from the post A, the form and arrangement of which will be hereinafter more fully described. At or near its lower end the rod at is pivotally connected with the rack 6 or an arm 7, laterally projected therefrom. The rack 6 is arranged to reciprocate longitudinally in a suitable vertical guideway 8 upon the post A. A pair of arms 9 9, also laterally projected from the post A, support in suitable bearings a trunnion l O, which carries a gear 11, which engages with the rack 6. Mounted and free to rotate in suitable bearings is a shaft 12,

. pulley 17, to which power is applied to drive it constantly in the same direction by means of the usual belt. The end'of the sleeve 16 adjacent to the pinion 15 is provided with the (preferably rectangular) notches 18, which engage with correspondingly-shaped projections 19 from the hub of the pinion 15, forming a clutching device, which is normally held in engagement by a suitably-placed spring 20, which, as shown, bears against the sleeve 16 and standard 14. The sleeve 16 further carries a comically-faced disk 21, above which is supported a similar disk 22, the conical face of which is oppositely inclined and which is mounted upon a trunnion turning in suitable bearings in the swinging lever 23, conveniently fulcrumed on post A at 24.. The lever 23 is supported by a spring 26, which is conveniently secured to one of the arms 9. The spring 26 normally holds the lever 23 in such position that the disks 21 and 22 are not in contact with each other. The lever 23 is in the path of the rigid arm 27, projected from the rack 6. An operating-treadle 28 is provided, which is arranged to rotate the shaft 29, which carries a latch 30, which is adapted to engage with the outer end of the lever 23 and hold the disks 21 and 22 in contact with each other and in such position that the clutch above described is prevented from engaging to rotate pinion 15. A suitably-placed spring 35 is provided, conveniently supported by the arm 36 and connected to the upper end of rack 6, against the action of which the rack 6 is'moved downward and which acts when the pinion is released by the clutch, as hereinafter described, to again raise the rack b and by means of the rod 4 to bring the horn into a convenient position for adjustment in a shoe upon a last or spindle 1.

The correlative function of the several foregoing features can be best understood by a description of their operation.

Then the rack 6 is at the limit of its upward movement, the horn is in a convenient position for adjustment on the last, and the lever 23 is held by the latch in position to prevent the engagement of the clutch, as hereinafter described. To start the horn-actuating mechanism, the operator depresses treadle 28, rotating shaft 29, and with it the latch 30, which allows the lever 23 to be raised by the action of spring 26 until the disks 21 and 22 are separated, when the notches 18 on the sleeve 16 are brought into engagement with the projections 19 on the hub of the pinion 15 by the action of spring 20, and the pinion 15 is set in rotation, rotating the gear 11 in the direction necessary to depress the rack 6 until by the connecting-rod 4 the born 2 has been drawn from the shoe, completing the relasting operation. hen the rack b has been sufficiently depressed to secure the above result or slightly before that time, the arm 27 is brought in contact with the lever 23, and a further downward motion of the rack 6 depresses the lever 23 until the disk 22 is brought in contact with the disk 21 and forced down on the same a sufficient distance to cause the clutch to disengage and to bring the latch 30 (which is held in position by the spring 34 and a suitable stop 32) over the end of the lever 23, which holds the clutch out of engagement until the latch is again tripped by the depression of the treadle 28. When the clutch has been disengaged, as above stated, the spring 35 again raises the rack,

the gearll and pinion 15 being rotated thereby in an opposite direction until the horn is again in position to be adjusted upon the last.

We will now describe the arrangement (shown in the drawings) whereby as the hornoperating rod 4 is depressed it is made to change its vertical inclination to secure a downward and inward motion of the horn connection 3, so that the horn will tip gradually over the last and not abruptly, as when drawn by a vertical pull.

As already stated, the rod 4 extends through the slot 5 in the arm 36 and is pivot-ally connected with the rack 63. It will be noted that as the horn 2 is drawn down the rod 4willbe held against the innerend of the slot 5, which is conveniently provided with a friction-roll 40 and which acts as a guide for the downward motion of the rod 4. The friction-roll 40 is projected laterally beyond the point of connection of the rod 4 and arm 7, the arrangement being such that as the rod 4is depressed while held against the roll 40 the bearing-point of roll 40 is transferred along the rod 4, causing the rod 4 to change its vertical inclination as itmoves downward, giving the connection 3 an inward as well as a downward motion. The amount of the change in vertical inclination which the rod 4 receives, as above explained, depends upon the difierence in the lateral position of roll 40 and the point of connection of rod 4 and arm '7, which may be conveniently adjusted by means of the adjustment-holes 71 along the arm 7, in either of which the rod 4 may be secured.

The slot 5 may be conveniently elongated, as shown, to allow sutficient lateral play of rod 4 to enable the operator to adjust horn 2 upon shoes of different sizes; but such provision would be unnecessary where a flexible shanked horn was provided.

The operation of our invention has already been sufficiently described; but we wish to say that we do not consider the same limited to the details of mechanism herein shown; but

We claim as novel and desire to secure by Letters Patent of the United States- 1. In a relasting-machine, the combination with a suitable last-support, of a shoe-horn, constantly-running power-driven mechanism for depressing said horn, automatic means to disconnect said horn from the power mechanism at the limit of its downward stroke to permit the manual raising and adjusting of said horn in a shoe, and means under the control of the operator to connect the horn and p0 wer mechanism, substantially as described.

2. The combination with the associated parts of a relasting-machine of a verticallymovable horn-operating rod, and a guide for changing the vertical inclination of the hornoperating rod, through which said rod passes and which is arranged to bear against said rod at a point which is transferred along said rod by its down ward motion, substantially as described.

3. The combination with the associated parts of a relasting-machine of a verticallymovable horn operating rod, a guide for changing the vertical inclination of the hornoperating rod, and a device for adjusting the extent of the change in inclination of said rod by said guide, substantially as described.
